To all 'whom 'it may concern: made inone piece from cast iron. Some' en- Be it known that I, OTIs N. TERRY, a citignes, however, are built with the cylinders zen of the United States, residing'at ALin-1' separate from the saddle, the saddle being coln, in the county of Lancaster andvState a smgle integral casting, all three parts beof Nebraska, have invented certain new and ing made of cast iron. In these' forms ci' 60 useful Improvements in Locomotives, of Construction the frames of the locomotive which the following is a specioation, are bolted tO- the Saddle and are Continuous The object ofmy invention is to provide from end toA end of the locomotive. In some an improved locomotive frame and improvelnstances where the cylinders consist of sepaments in the manner of constructing and selrate castings the Vframes are bolted between 6 curing together the saddle, frame members the cylmder castings and the saddle.

For the purpose of securing' the Know built in this country -are constructed separatekhalves ofthe saddletogether I pro- 55 with the cylinder" and half of the saddle `Vide each half with flanges l projecting from 11o the J[ront and back walls 2. At each side of the front and back end of the saddle I provide projecting lugs 3 reinforced by horizontal webs it'also projecting from the end wall. The ttanges l are continued along the meeting edges of the webs a and bolts 5 serve to hold the halves of the saddle securely together. 'lfhe lugs 3 are odset about midway their height, as shown at 6 in Figs. 1 and 2, thus forming a channel upon the outer faces vot the lugs,.the top and bottom walls of which channel are in vertical alinement with the upper and lower surfaces or' the lugs. Bolt holes extend lfrom the upper and lower surfaces ot' the lugs to the channel referred to, andl the channel is of sufticient width to accommodate the nuts 7 upon the bolts which pass through the upper and lower sections oilf' the lugs and secure thereto the upper and lower rails t), l0, ll and l2 ot the frame. For the purpose of securely holding' the frame lrails to the lugs l provide vthe ends of the-rails and of the lugs with projections 13 and llt, the length ot these projections being such as to leave itcyways between them for the reception of keys l5 whereby the ends of the trame rails are forced into intinmtecontact with the saddle. The bolts lt in connection with the keys l5 serve to hold the trame rails and lugs against relative movement in any direction.

tty means ot the construction 'above ttescribed the sides ot' the saddle are Vtrex and unobstructed by the side .trames of the locomotive, thereby rendering it possible to pro vide a direct passage 1T trom the `steam chest through the saddle lor the exhaust steam. In thisconstruction the saddle terms an intermediate part ot the engine trame instead otl being7 as is the usual practice, an extra member cmlnfaced between the continuous side trames. 'l`he. live steam pipe 1H may be. placed entirely outside, ot'. the smoke-box7 or may be partly inside. ot the smoke-box and have. the lower end project i through a hole in the .side thereof.

'l`he saddle is provided with l'orwardly and real wardly projecting lugsl or tlanges. 2O provided atI their ends with projeetilmsl l t'ornnng al shoulder lying in a vertical plane and theI trame members 2; are provided with projections ll forming coni-ting lshoulders.

The cylinder and steam chest castings 26 are formed with horizontal shoulders 27 which coactwith the upper and lower surfaces ot' projecting ribs 28 formed upon the sides ot' the saddle` and the saddle and cylnder are formed with vertical overhanging shoulders 29 and 3() which are forced into intimate contact by means of a key 31 received between vertical shoulders 32 and 33 upon the saddle and cylinder respectively. Boltsf) servev to hold the cylinders to the saddle. An exhaust steam passage 36 is cored in the saddle and a communicating passage 37 in the steam chest. In order to avoid the difficulty of accurately'titting the end of thesteam passage 37 to the end of the steam passage 3G, T provide a flexible coupling member 38 adapted to be received between the steam chest and saddle at the poi'. of `innction of the passages 36 and 3T. Tl.v tlexiblecoupling 38 I preferably form of brass and provide it with an annular projecting rib 3S) whereby the coupling may be' readily compressed or expanded to accurately tit the space between the steam chest and saddle. 'lhe coupling is secured to the steam chest and saddle by means of bolts passing through suitable tianges. I construct the saddle ot' cast steel in order that it may etlectually serve its function as a part of the engine frame. -Thc cylinder and steaincliest castings may be of cast iron as is thc usual practice.

l would-have-it understood that I do not desire to limit myself to the precise construc-` i tion and arrangement of parts shown in the ,lrawings and herein described, as 'various moditit'fations or alterations may be made without departing from my original invention.
